Fish oil supplementation as an omega-3 fatty acid source during gestation: effects on the performance of weaned male goat kids.

The aim of this study was to evaluate the effects of fish oil supplementation, as an omega-3 fatty acids source, to ration of does in the different periods of pregnancy on the fattening performance of kids after weaning. Eighty German Fawn × Hair crossbred does were randomly divided into two groups; half were given fish oil in the first half of pregnancy (FO group), while the other half were given saturated fat (PF (control) group). Then, the goats in the FO and PF groups were randomly divided into two subgroups, and half of the goats were fed fish oil during the second half of pregnancy (FO-FO and FO-PF groups), while the other half was fed saturated fat (PF-FO and PF-PF groups).

PRNP gene polymorphisms in main indigenous Turkish goat breeds.

The polymorphisms of the PRNP gene influence the susceptibility to scrapie in goats. In this study, caprine PRNP gene was analysed in a total of 249 individuals from three main indigenous goat breeds of Turkey: Anatolian Black, Angora and Kilis. We focused on the Anatolian Black breed, which represents 97% of the goat population in Turkey and compared the data of samples originated from different geographical regions.
